HEATING-DRUM.

SPECIFICATION forming part of Letters Patent No. 793,368, dated June 27,1905. Application filed June 30, 1904. Serial No. 214,790.

To all whom it may concern Beit known thatl, FRANK i\ I.(5ri\n.u.\N,acitizen of the United States, residing at Alma (Jenter, in thecounty of Jackson and State of \Visconsin, have invented a new anduseful Heating-Drum, of which the following is a specification.

This invention relates to heating drums-or radiators of that class whichare specially adapted to be used in connection with stoves, the sameforming a part of the means for the passage of the products ofcombustion from the stove or place of combustion to the final point ofexit.

The invention has for its object to provide a device of this class whichshall be simple in construction, easily applied to an ordinarystovepipe, durable, and efticient in operation.

\Vith these and other ends in view the in vention consists in theimproved construction, arrangement, and combination of parts, which willbe hereinafter fully described, and particularly pointed out in theclaims.

In the accompanying drawings has been illustrated a simple and preferredform of embodiment of the invention, it being understood, however, thatI do not necessarily limit myself to the precise structural detailstherein exhibited, but reserve the right to such changes, alterations,and modifications as come fairly within the scope of the invention andwhich may be resorted to withoutdeparting from the spirit or sacrificingthe utility of the same.

In said drawings, Figure 1 is a vertical sectional view of aheating-drum constructed in accordance with the principles of theinvention. Fig. 2 is a horizontal sectional view taken on the line 2 E2in Fig. l.

(orresponding parts in both figures are indicated by similar numerals ofreference.

The heating-drum of my invention consists, primarily, of a casing 1,preferably cylindrical in shape and provided in its upper and lowersides with openings 2 and 3, surrounded by the flanges or collars 4: 5,by means of which the drum may be conveniently connected with joints ofordinary stovepipe, as indicated at 6. \Yhen thus adjusted upon orconnected with the stovepipe, the drum 1 will obviously form part of thesmoke-passage. \Vithin the drum l is disposed a diaphragm 7, which is ofless diameter than the drum, between the outer wall of which and theedge of the diaphragm is an annularspace or ogening 8. The diaphragm Tis provided on its under side with radiating arms 9, which extend fromthe center of the diaphragm and beyond the edge of the latter, said armconstituting means upon which the diaphragm is supported about centrallyin the drum or casing. The arms or supporting members 9 ter minate incontact with the wall of the drum, and their outer extremities are bentor deflected, as shown at If), all in the same direction. Arms 11,similar to the arms 9, butdisposed intercurrently therewith, are mountedupon the upper surface of the diaphragm 7, said arms 11 likewise havingbent ends 12, deflected in the same direction as the ends of the arms 9and terminating in contact with the wall of the casing or drum.

It will be understood that in operation prodnets of combustion ascendingfrom the place of combustion and passing into the drum through theopening 3 at the bottom thereof will be deflected in the direction ofthe outer wall of the drum by the diaphragm '7, the arms 9, having thebent ends 10, serving to deflect the smoke laterally, and thus set up aspiral movement, which will be augmented by the bent ends of the arms 11upon the upper side of the diaphragm until the products of combustionescape through the opening 2 in the top of the drum or casing. Thiswhirling or spiral movement will not only have a tendency to improve thedraft, but will also distribute the products of combustion, which enterthe casing in a highly-heated state, toward the outer walls of saidcasing, whereby the heat will be freely absorbed and radiated into theroom where the device is located. hen, as is the intention, theheating-drum is disposed in close proximity to the stove, the diaphragm7 will arrest and deflect the burning gases ascending from thecombustionchamber and without interfering with the necessary draft willtend to moderate the latter and to cause all the heat units to beextracted and utilized, thus enabling a large her.

saving in fuel to be effected without loss of available heat.

Under the construction illustrated in the accompanying drawings each ofthe flanges or collars 4E and 5 is composed of an inner member 15,having a lug or flange 16, which eX- tends through and abuts against theinner side of the top or bottom of the drum or casing, as the case maybe, and an outer member 17, which is connected to the inner member bymeans of rivets 18 or other suitable fastening means, the edge of theopening 2 or 3 being in either case upset, so as to form a flange 16,extending between the inner and outer members 15 and 17, thus forming astructure of great strength and simplicity and whereby the several partsare securely retained in the proper position with relation to eachother. At the bottom of the casing the outer flange member 17 is longerthan the inner flange member 15, so that the connecting-joint of theStovepipe may be inserted within said outer member and abut upon saidinner mem- At the top of the casing the construction is reversed in thatthe inner flange member 15 is the longer, thus enabling it to beintroduced into the abutting stovepipe-joint 6, the end of which abutsupon the outer flange member 17. By this simple construction andarrangement of parts the device is materially strengthened and leakageof smoke at the joints of the device is rendered practically impossible.

It is obvious that by the construction herein employed the device may bereversed and utilized with either side uppermost. Another practicaladvantage of the device is that the upper side of the drum may beutilized for ,ees

the purpose of heating plates or articles of food which may be placedthereon.

Having described my invention, I claim- 1. A heating-drum consisting ofa casing having an inlet in its lower and an outlet in its upper side, adiaphragm supported within the casing and of less diameter than thelatter, and radial supporting-arms for said diaphragm having bent ends,all deflected in one direction and terminating in contact with the wallof the casing.

2. A heating-drum consisting of a casing having an inlet in its underside and an outlet in its upper side, a diaphragm of less diameter thansaid casing and supporting-arms upon the under side of said diaphragm,said arms radiating to the outer wall of the drum and having bent endsall deflected in one direction, and radial arms upon the upper side ofsaid diaphragm disposed intercurrently with relation to thesupporting-arms and having bent ends deflected in the same direction asthe ends of said supporting-arms.

3. In a heating-drum, the combination with a cylindrical casing of adiaphragm of less diameter than said casing, said diaphragm beingprovided on its upper and under sides with radiatingintercurrently-disposed arms extending beyond the edge of said diaphragmand having bent ends all deflected in the same direction.

In testimony that I claim the foregoing as my own I have hereto affixcdmy signature in the presence of two witnesses.
